Java获得键盘输入的两种方法

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;

public class MainClass
{
        public static void method1()
        {
                //使用Scanner
                Scanner scanner=new Scanner(System.in);
                System.out.print("Please input a number:");
                int num=scanner.nextInt();  //获取整数值
                System.out.println("The number you input is:"+num);
                System.out.println("----------------------------");
                System.out.print("Please input some character:");
                String str=scanner.next();  //获取字符串值
                System.out.println("The string you input is:"+str);
                
        }
        public static void method2()
        {
                //使用BufferedReader
                try
                {
                        BufferedReader reader=new BufferedReader(new InputStreamReader(System.in));
                        System.out.print("Please input a number:");
                        String str=reader.readLine();  //获取字符串
                        System.out.println("The number you input is:"+str);
                        
                } catch (IOException e)
                {
                        e.printStackTrace();
                }
        }
}
